Common questions about link generation, QR codes, UTM tracking and more.
A WhatsApp Click-to-Chat link opens a direct conversation with a specific phone number on WhatsApp — without the recipient needing to save your contact first. It uses the format https://wa.me/[phone] and can include an optional pre-filled message. These links work on both WhatsApp Web and the mobile app. They are ideal for adding to websites, email signatures, social media bios, and digital ads to instantly start customer conversations.
UTM parameters are short tags appended to any URL that tell analytics platforms like Google Analytics exactly where a visitor came from. There are five standard parameters: utm_source (e.g., "facebook"), utm_medium (e.g., "cpc"), utm_campaign (e.g., "spring_sale"), utm_term (paid keywords), and utm_content (to A/B test creatives). Marketers use them to measure which channels and campaigns actually drive conversions — not just clicks.
QR codes generated on InstantLinkHub can be downloaded as PNG in five sizes: 200×200, 300×300, 400×400, 500×500, and 1000×1000 pixels (HD). PNG is the right choice for digital use — websites, emails, and social media. For physical print materials like business cards, banners, or packaging, always use the 1000×1000 HD option and then convert it to a vector format (SVG or EPS) in a design tool before sending to the printer.
A mailto link is a special HTML anchor that opens the user's default email client — Gmail, Outlook, Apple Mail — with the To, Subject, and Body fields already filled in. The format is mailto:you@example.com?subject=Hello&body=Your+message. You use it by setting it as the href of any link or button. Our Mailto Generator handles all the URL encoding automatically, including spaces and special characters, so you just copy and paste the result.
No — and this is a core design principle, not just a policy. Every tool on InstantLinkHub runs entirely client-side: the logic executes in your browser and nothing is transmitted to our servers. Your phone numbers, URLs, messages, and email addresses exist only in your browser tab and disappear when you close or refresh the page. You can verify this yourself by opening your browser's DevTools Network tab while generating a link — you will see zero outbound data requests.
